Desktop NAS with RAID 1

The Buffalo LinkStation 220 is a two-bay desktop NAS that ships with two 4TB drives pre-configured in RAID 1, providing 4TB of usable mirrored storage. It targets home users and small offices that want automatic backup and personal cloud access without subscription fees. A single Gigabit Ethernet port and one USB 2.0 port handle network and local expansion.

Sustained load behaviour

The dual-issue ARM processor running at 800MHz and 256MB of DDR3 memory manage file transfers and background RAID maintenance at Gigabit line rate. During long copy jobs or multiple simultaneous streams the CPU becomes the limiting factor, so throughput settles below the network maximum rather than bursting higher. RAID rebuilds after a drive failure proceed at a pace dictated by the processor and SATA 3Gbps links.

Thermals noise and power

Maximum power draw is rated at 48W from a 100-240VAC supply, and the unit is specified to operate between 5°C and 35°C. The closed chassis relies on passive convection and a low-speed internal fan, so acoustic output stays at background-office levels during normal file serving and backup tasks.
